When 13-year-old Hit-Girl (Chloe Moretz) uttered the C-word before battering the baddies, it guaranteed it was a box-office smash and invited a sequel.
Now 15, Hit-Girl has been grounded by her dead father's friend who promised to look out for her.
But, given all the hassles of dealing with bullies at school, she's itching to lock loins with Kick-Ass (Aaron Taylor-Johnson).
He also has problems since his worldwide fame has encouraged a host of wannabe super-heroes in silly suits to form the Justice League fronted by former mob thug Colonel Stars and Stripes played in crazy-mode by Jim Carrey.
They need Kick-Ass, he needs Hit-Girl. The spark that fuses the show is provided by the return of Red Mist (Christopher Mintz-Plasse), now called Motherfucker, who dresses up in his dead mother's fetish gear.
Out for revenge and funded by his daddy's fortune, he hires some bad-asses to form a legion of evil, including the notorious Mother Russia who sports hammers and sickles on her nipples.
Clearly relying on bad taste - rather than its original brattish wit - it's simply super-charged the sexism with an offensive rape scene and will no doubt put bums on seats since Carrey has criticised it for "gratuitous violence."
